Q: No sound or input, output and microphone options.
Recently my Macbook Pro (13", 2014) has seem to lost all sound and been mysteriously put on mute. I cannot alter my volume or turn off mute. When I open up Preferences > Sound I have no sound input or output options and when opening up MIDI I have nothing there either.
I have tried just about anything you can name, restarting, restarting in safe mode, reset the PRAM, reset the SMC, deleted several files, updated software from Mavericks to El Capitan and even tried cleaning the headphone port. I have no red light in the headphone port either.
Anyone have any other suggestions to fixing my problem?
I would also like to avoid having to take it in and replace parts as I am no longer under warranty.
Thanks.
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
